Labrador retrievers may be black, brown, or golden in color. Although each color may breed true, many different outcomes occur if numerous litters are examined from a variety of matings, where the parents are not necessarily true-breeding. The following results show some of the possibilitiesblack × brown ? all blackblack × brown ? 1/2 black 1/2 brownblack × brown ? 3/4 black 1/4 goldenblack × golden ? all black black × golden ? 4/8 golden 3/8 black 1/8 brownblack × golden ? 2/4 golden 1/4 black 1/4 brownbrown × brown ? 3/4 brown 1/4 goldenblack × black ? 9/16 black 4/16 golden 3/16 brown A.
